Once he was able to start play, Woods shot 2 over par through 11 holes and grasped his back a couple of times. He withdrew at the 12th hole.

“It’s frustrating that it started shutting down like that,” Woods said in the parking before driving away. “I was ready to go, had a good warmup session the first time around. I stood out here and got cold and everything started to deactivate.”

Woods was coming off the worst round of his professional career, an 11- over-par 82 Friday at the TPC Scottsdale course, causing him to miss the cut at the Waste Management Phoenix Open.

A seven-time winner of San Diego's tournament, Woods' presence all but guarantees extra local and national attention on the event at Torrey Pines. He last won here in 2013, but missed the cut last year.

Another fan favorite, Phil Mickelson, struggled to a 3 over par through his first seven holes.

For fans heading to the final three rounds, the main entrance has been changed to the Torrey Pines Gliderport at the south end of the club. Tournament organizers say that will allow them to open more entrance gates and get fans inside faster.

The hitch is that once patrons clear the gates, they'll be astride the 12th tee and 13th hole of the South Course, which means a long walk for those heading to the center of the action, or the North Course.

Parking will not be available at the gliderport.

Fans can park at SeaWorld San Diego or the Del Mar Fairgrounds for $20 and ride a shuttle to the course.

People will not be allowed on the shuttle if they are carrying items that are banned on the courses, including backpacks, large purses or tote bags, coolers, food and beverages, and cameras.

On Saturday and Sunday, parking will also be available at the Scripps Center for Integrative Medicine, 10820 N. Torrey Pines Road, for $30, or the parking structure at 3506 Cray Court for $25.

Play continues on both courses Friday. The initial field of 156 will be reduced to the low 70 and ties following the conclusion of Friday's second round.

The Saturday and Sunday rounds will be held on the South Course. The winner will receive $1.134 million. When the tournament was moved to Torrey Pines in 1968, the purse was $150,000, with winner Tom Weiskopf receiving $30,000.
